No, because they're hardly enforced. China has been blatantly dumping a buttload of products for decades and the U.S. has been asleep at the wheel as it continues to hollow out our domestic manufacturing industries even further.
Dumping means losing money. China is winning because they give businesses low interest loans from a state owned bank (or invest capital from a state fund) to expand production. Factories are profitable the whole time, they just don't waste money and time getting private loans.
America can't do that because the government takes bribes from banks and believes in Friedmanite ideology where state investment is evil. It's a great opportunity for Europe to copy China and become independent.
